This quest is a must right from the get-go unless you've decided to play as a tank. Aveline will join you after you start on this quest. Visit the Viscount's Keep and talk to Aveline. This will unlock The Way It Should Be quest.

This is also a good time to find the Bottled Scar 5:34 Exalted in the Viscount's office, it's part of a find and deliver quest.
